Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. But don't worry! This issue is being tracked by the KDE developers at: https://bugs.kde.org/show_bug.cgi?id=225209
Once fixed in KDE, it will be included in Kubuntu once the KDE version the fix is in in reaches Kubuntu.

Thanks!
